    摘要: In an embodiment of the invention an integrated circuit includes a memory array having a first plurality of decoded lines traversing across the memory array and a pair of dual-mode decoders, each decoder coupled to each of the plurality of decoded lines a respective location along said decoded lines, such as at opposite ends thereof. Both decoder circuits receive like address information. Normally both decoder circuits operate in a forward decode mode to decode the address information and drive a selected one of the decoded lines. During a test mode, one decoder is enabled in a reverse decode mode while the other decoder remains in a forward decode mode to verify proper decode operation and integrity of the decoded lines between the decoders.

    摘要: An exemplary amplifier circuit includes a first group of spatially distributed final amplifier stages having a first configuration, and a second group of spatially distributed final amplifier stages having a second configuration different than the first configuration. Both groups share the same control node for their respective final amplifier stages, and both groups share the same amplifier output node. Each group is typically enabled at a time that the other is disabled. In certain embodiments incorporating a memory array, only one critical analog node must be routed throughout the memory array.
